CARL M. WANGSNESS, OF FINLEY, NORTH DAKOTA.

LOADER.

'1 b all whom it may concern Be it known that I, Cant M. VVANosNnss, a citizen of the United States, and a resident of l inley, in the county of Steele and State of North Dakota, have made certain new and useful Improvements in Loaders, of which the following is a specification.

My present invention relates to leaders and more particularly to devices including means for gathering and conveying hay and grain in the field to a wagon, cart or vehicle in connection with which the loader is moved from place to place.

The object of my invention is to provide a loader embodying a plurality of gathering teeth, each of which includes in part a conveyor and is so constructed that the conveyer may be effectively adjusted and protected in use.

In the accompanying drawings which illustrate my invention Figure 1 is a plan view illustrating the parts of the loader pertaining to my invention, the supporting trucks and certain portions of the frame being removed for purposes of better illustration, Fig. 2 is a side elevation of the parts shown in Fig. 1, Fig. 3 is a perspective view of one of the intermediate conveyor supports, Fig. is a central longitudinal section through one of the teeth, Fig. 5 is a plan view of an intermediate portion of one of the teeth, on an enlarged scale, the conveyer being removed, and Fig. 6 is a vertical transverse section taken substantially on the line 66 of Fig. 5, showing portions of the conveyer in place.

Referring now to these figures, a loader constructed in accordance with my invention essentially comprises a plurality of longitudinal parallel teeth A, secured in spaced relation by means of transverse supports B and C respectively connecting the series of teeth at an intermediate point and at their inner ends, these transverse connecting members 13 and 0 being secured at their ends to the usual supporting frame of which portions of the side bars l) are shown in Figs. 1 and 2. In practice the frame may be composed of the side bars 1) and certain braces, all of which are well known, are supported by adjustable wheeled trucks also well known and which I have purposely omitted in order that the remaining parts and particularly those parts upon which my improvements are based may be better seen and more fully understood.

shown more particularly in Figs. 4, 5 and 6 each of the teeth A is hollow throughout its length and tapers at one end to a point 0, its upper wall being provided with an opening 0 adjacent to the point and its side walls having longitudinal slots below the opening (1. A sprocket wheel E is journaled on a transverse pin a which extends through the side walls slots (1 and is engaged by adjusting screws 6 operating in a direction toward the point. of the tooth through the laterally projecting and internally threaded lugs c and bearing against the laterally projecting end portions of the pin a. This s 'n'ocket 1*] receives thereabout the forward portion of a conveyor F in the form of an endless chain having a series of outwardly projecting spurs located at spaced points therearoluul, the inner or rear end of this conveyor passing around a sprocket wheel YE mounted in the rear end of the tooth and secured upon a shaft G which is journaled through the rear ends of the series of teeth as particularly shown in Fig. l and is connected by a universal joint at (.i to a suitable source of power such as the running parts of the vehicle in front of, or along which, the loader is disposed. In this manner the upper run of each of the conveyor chains F is guided and rests upon the upper wall of the respective tooth, these upper runs of the several conveyors coopcrating to convey the hay or grain picked up by the tooth points, rcarwardly to its inner end. In this manner the several chains are held in the same horizontal plane and prevented from sagging, it being seen that their return portions or runs travel in the hollow teeth, each tooth having its side walls bent to provide intermediate lateral ofi'sets, as seen at 1; in Fig. 6 upon which the return portions or runs of the conveyors travel in order to prevent the latter from sagging or lowering to such an extent as to permit their spurs f to drag along the bases of the teeth.

If desired a plurality of gathering fingers .l 'l may be supported upon a transverse shaft- I and depending therefrom between the points of the several teeth A, the said shaft being journaled through the forward portions of the frame side bars D and having an end crank i to which a suitable connecting rod under control of the operator may be connected. It will thus be seen that at desired intervals the gathering fingers I-I may be raised to the posit-ion indicated in. dotted lines in Fig. 2 in order that the collected grain or hay may be moved upwardly on the series of teeth A. I may also provide a plurality of intermediate convey-ere J, each of which is a substantial duplicate of one of the above described conveyers F, and each of which is carried by sprocket wheels in the forward and rear portions of brackets K one of which is shown in detail in Fig. 3, the forward and rear ends of these brackets being seated on and secured to the transverse connecting members B and C respectively and the sprocketwheels in their rear end being secured upon the driven shaft G which also actuates the sprocket wheels E.

Thus in operation the conveyer-s in the several teeth will be effectively supported and protected against undue wear, sagging, and undesired contact of the several spurs with the teeth, both by virtue of the particular construction of the several teeth and the adjustment of the forward sprocket wheels E in the hollows thereof.

I claim:

1. In a loader of the character described, the combination of a plurality of gathering teeth, each of which is hollow throughout its length and tapers to a point at its outer end, each of said teeth having an opening in its upper wall adjacent its point and slots through its side walls below the opening, a pin extending transversely through the side wall slots, usting screws threaded through portions of the teeth at its opposite sides and bearing against the end portions of the pin, a sprocket wheel journal ed on the pin, a driven shaft journaled through the inner ends of the several teeth, a sprocket wheel secured upon said shaft within the inner end of each of the teeth, a conveyer carried by each of the teeth and consisting of an endless chain having outwardly projecting spurs and having its ends passing around the said sprocket wheels, the inner run of each chain passing within the hollow of its respective tooth and having its outer run disposed upon the upper wall of the tooth, and each of the teeth having its side walls bent and offset to provide longitudinal shoulders upon which the lower run of its respective chain is carried to prevent contact of the spurs with the base of the tooth.

2. A loader of the character described comprising a plurality of gathering teeth, each of which is hollow throughout its length and tapers to a pointat its outer end, and a convey-er mounted in the hollow of each tooth all for the purposes described.

3. A loader comprising a plurality of teeth hollow throughout their length and pointed at one end,,each of the teeth having forward and rear sprocket wheels mounted in the hollow thereof, a conveyer consisting of an endless chain provided with spurs and extending around the said sprocket wheels, the outer run of the chain being disposed upon the upper wall of the tooth and the inner run thereof passing through the hollow of the tooth and each tooth having longitudinal side shoulders therein upon which the inner run of its respective chain is supported in its travel for the purpose described.
